COMBINED CLOCK AND LETTER BALANCE.

Application leid November 28, 1922. Serial No. 603,844.

To au wlw/m t may concern.:

Be it known that I, Go'rrrnrno GNTHER, a citizen or' the German Republic, and resident ot' Schwenningen-on-the-Neckar, tiermany, have invented a new and use tul Gombined Clock and Letter Balance, for which has been tiled an application in Germany, dated March 8th, 1922, and of which the following is a specification. i

This invention relates to the combination, of a clock with a letter-balancein such a manner that the casing of the clock encloses also the weighing mechanism and the dial of the clock has a scale with a slot throu h which a small hand co-operating with tllie scale projects. The scale pan, or the lettersupport respectively, is located above the clock-casing, and the weighing-mechanism `is arranged between the clock-work and the dial so that the otherwise empty space4 around the hand shafts is utilized.

The arrangement may be such that the scale pan and its carrier or support may either be removed from the casing or may he rearwardly slewed so as to be out of the way when the letter-balance is not used. Besides, the Weighing mechanism may he prevented from swinging during that time,ror may be locked respectively, which may be eifected, for instance, by thek slewable, i. e. slewed, scale pan support, as is fully described hereinafter.

My invention is illustrated, by way'of eX- ample, in the accompanying drawing, in which Figure 1 is a front view of the combined clock and letter-balance, the foot of the clock and the greatest portion of the dial being removed and'chietly the weighing mechanism being shown infront View. l? igure 2 is a vertical section'tl'irough the clockwork, the lowest portion of the casing. inclusive the foot, being broken away. Figure 3 is a front view of the complete clock, ready for weighing, and Figures l and 5 show some details which also are full).T treated hereinafter.

The clock is generally a clock with a base plate, maybe with feet, which is to stand on a horizontal surface, and its casing is correspondingly shaped. The clock-work is located and supported in known manner between the front wall or plate p and the rear wall or plate q, and in front of the wall or plate 79 is the dial a` which has a curved slot b through which projects the pointed end olf the hand c that co-operates with a scale extending along the slot and showing the weights. In liront o'f the whole is a glassplate, as shown in Figure 2.

The weighing mechanism arranged between the clock-work plate y) and the dial a., and above the casing of the clocl; is the weighing pans which is secured to a standard or stem r. This is inserted into a sleeve ey forming the upper end of a vertically movable angular member CZ supported. and guided by a'lower link u` and by an upper link fu forming an arm of a kind of belcrank lever `the other arm fw of which is curved (Figure l) and extends around i the shafts of Ythe clock-hands. The lower end of the arm w forms the indicating hand c co-operating with the scale at the slot Zi., and a downwardlyextending lug of the arm fr0 has attached to it a poise g which is deviated to the right when the pan s is loaded. Owing to the upper portion of the lever arm w being curved, it is prevented from c ntacting with the hand shafts ofi the clock.

The weighing mechanism shown in the drawing' is'merely an example. lit is obvious that an equivalent one may be inthe space provided for its reception, and it is. also obvious that a weighing mechanism rhaving a spring instead of a poise may be employed.

w, Figure 2, is an abutment or stop which co-operates with the horizontal portion oi the member d of the weighing mechanism and is so located with respect to it that the indicating hand c points just to zero.y

If the weighing mechanism need not be employed, the standard or stem r with the pan s may be taken oil; the clock, i. e. drawn out of the sleeve e, or the arrangement maj.' be such that the stem with the pan may be rearwardly slewed, as shown in F and described hereinafter. It is also d able to prevent the weighing mechanism from oscillating when not being used, and for that purpose I have provided the form ont construction shown in Figures t and 2 a horizontal sleeve L at the inner surface ot the rear wall of the casing of the clock. This sleeve is intended to receive the stem f of the pan after these parts have been taken off the sleeve the length of the stem being such that its end comes to lie just below the sleeve e whereby the weighing mechanism is locked. At

the same time the Weighing pan s is out of the Way, it being preserved beiind the casing in thatJ position indicated by dotted lines in Figure 2, I Wish it, hoivever, to he understood. that also another place may be chosen to hold the pau When eut ot use. for instance that place indicated hv the dotted circle at the right ot VFigure Il. There is then provided any suitable intermediate member acted on by the stem ot the pan and acting in its turn `for instance upon the poise so as to check the Weighing mechanism. or prevent it `from unnecessary oscillations respectively.

letc-rriug noivto Figure 5, the lower end oi the stem i" of the pan s has a vertical .slot j through which extends a horizontal in vi atlired in the sleeve e. The stem may, husq he lifted as tar as permitted by the ength et the slot. The sleeve has a recess ,1/ at its rear edge and the lifted stem may he rearwardly turned upon the pin i and slevfed down into that recess. When it assinnes the position shown in dotted lines in 'Figure rhere may be provided behind r :e slr-eve a special supporting member f 'for the stem. and an elastic means may be rrovided holding the stem tast in its horirfcental vaosition. lt is. finally, obvious that die horizontally slev-fed stem (Fig. forms :it the saine time a checking means for the sleeve and, thus` for the Whole Weighing n; chanism which cannot make unWished-tor oscillations.
